A cannula having a hollow metal tube for injection of liquids such as an anesthetic, or RF energy, into a patient. A thermocouple or other temperature sensor is located at the bare tip of the cannula, and a wire for the temperature sensor extends along the length of the cannula, preferably in a groove formed in the tube, or through a passageway formed in the tube. An outer insulation layer covers the tube and wire. Thus, a single device serves as both a cannula and an electrode.

The invention relates to a clip-like implant for osteosynthesis of at least two repositioned bone fragments, with at least two retainer web sections and with one connection web section connecting the retainer web sections, wherein the free ends of the at least two retainer web sections can be at least partially fixed in a respective one of the two repositioned bone fragments. Advantageously the clip-like implant has a C-shaped cross section, in which the first and second retainer web sections each enclose with the connection web section an angle (w, w′) between 75° and 90°, and the free ends of the at least two retainer web sections are designed as inwardly directed points.

A minimally invasive system includes a bone screw and a tissue retractor having distal and proximal end portions and a partial pathway therebetween. The tissue retractor is removably couplable to the bone screw. An instrument has distal and proximal end portions and a hollow cavity and is removably couplable to the tissue retractor. A drive shaft has a diameter less than a diameter of the hollow cavity and is rotatable with respect to the instrument. A counter-torque handle has gripping and an interlock end portions with an instrument interface releasably positioned within the hollow cavity at the proximal end portion thereof and rotatably fixed thereto in an assembled configuration. The interlock end portion also includes an open-ended slot having a width greater than the drive shaft diameter such that the counter-torque handle is movable to and from the assembled configuration while the drive shaft is within the hollow cavity.

A multi-component intraocular lens implanted in an optical system of a human eye includes one or more removable components, each component being foldable. One component acts as a base lens, including a flange with an aperture. Another component acts as a mid lens, including a tab which engages the aperture. A third component acts as a top lens, which engages the mid lens. Because the lens components are foldable, they may be inserted into the eye using an incision smaller than the diameter of the unfolded lens. The removable components may be used to correct various medical conditions of the eye, as well as to improve and enhance vision, and for cosmetic purposes.

An implant holder for removably retaining an implant during an implantation procedure includes a holder device having a frame defining a chamber. The frame may be configured for removable retention of an implant, such as the flexible bioprosthetic heart valve, substantially within the chamber. The removable retention of the implant to the implant holder maintains the implant in an orientation and shape suitable for implantation.

The invention describes substrates, such as prosthetics, films, nonwovens, meshes, etc. that are treated with a bioadhesive. The bioadhesive includes polymeric substances that have phenyl moieties with at least two hydroxyl groups. The bioadhesive constructs can be used to treat and repair, for example, hernias and damaged tendons.
